(Cl. 158-118) Theproduction and supply of the required On the accompanying drawing anexample of compressed or blowing air by means of mechania burneraccording to the invention is illustrated, cal devices for compressedair-gas burners which Figure 1 shows a longitudinal section, takenareknown up to the present time, such as comon line I I, Fig. 2,

A furtherdisadfield e when the alternating circuit is shut, and. vantage of thesedevices is to be found in the which magnetism causes the diaphragm ,f toinsuflicient mixing of gas and air, whereby the swing in a number ofvibrations resulting irom difierent air and gas streamlines flow onebeside the frequency of the alternating current. Herethe other withoutmixing intensively. by, an air movement is caused in the diaphragm l5 Bythis invention, the arrangement of all rochamber 9 in such a way thatthe fresh air is tating and sliding parts are made superfluous suckedinto-the diaphragm chamber 9 through owing to the fact that the requiredair is adopening (1 made in the air pipe 2', and opening h mitted intothe gas stream by a known electromade in the surrounding tube t, and isblown in magnetic diaphragm blowing apparatus.

In this way, the quantities of the and thegaseous fuel may be intermittently fed. separate air particles may beadjusted so that The mixing of the gas with air or oxygen takes anair-gas mixture which is in accordance with place in a known manner in amixing chamber the respective conditions will be produced.

The mixing chamber that the air-gas mixture existing herein,when is built in such a way that it serves as buffer the apparatus is inoperation, serves as shock for t a pulsations in Order to avoid flabsorber. It serves also for the purpose of de- 4,5 ing flame. creasingthe energy of the separate air particles A further feature of thisinvention consists avoiding hereby a flickering.

Still another feature of this invention is adjustableand secures thebase in its position based on the fact that the quantityof the after the amplitude of the vibrations of the diarequired andthereby oi the constituents of the phragm hav bee regulated.

- gas-air mixture is brought about by the regula- I claim:

fuel-gas and air consisting of a diaphragm and an electro-magnet adaptedto be excited by alternating current, said diaphragm being continuouslyvibrated by the electro-magnet for bringing one of the two constituentsinto the other, a mixing chamber, an inlet therein for supplyingfuel-gas, another inlet for supplying air, a diaphragm chamber one wallof which consisting of said diaphragm, the diaphragm chamber openinginto one of said inlets.

2. In an air-gas burner, a mixing chamber, a diaphragm chambercontaining a diaphragm electromagnetically vibrated by alternatingcurrent, a pipe connected with the diaphragm chamber terminating in thelower end of the mixing chamber the upper end of which is open, an

, inlet opening into the said pipe, and another inlateral inlets openinginto the said pipe for the air arranged between the mixing chamber andthe diaphragm chamber, and another inlet for the fuel gas arranged inthe lower end of the mixing chamber.

4. In an air-gas burner, means for mixing fuel gas and air consisting ofan electromagnetic vibration'diaphragm apparatus containing a diaphragm,an electromagnet and means for varying the distance between thediaphragm and the electromagnet.

5. In an air-gas burner, a hollow socket, an electromagnet, a diaphragmchamber, both arranged in the interior of the socket, a burner pipe, acap for closing the socket at the upper side and centrally bearing theburner pipe.

6. In an air-gas burner, a hollow socket, an electromagnet, arranged inthe interior of it, a threaded cap for the upper side of the socket, adiaphragm vibrated by the said electromagnet and connected to the lowerside of the cap, and a burner pipe centrally fixed to the upper side ofthe cap.
